What is the .GMK File Extension?

.GMK File Extension Description:

The file with a GMK extension is the project source file used in the GameMaker 7.0, developed by Mark Overmars. The application is used to create 3D and 2D games solely for Microsoft Windows operating systems.

The application incorporates a "drag-and-drop" feature, which allows users to create games without the need for source codes, like those used in programming languages. However, support is readily available if the user wishes to incorporate advanced features into their projects using such languages like Java and C/C++.

The .gmk file extension is the latest encrypted source file used in a GameMaker project. The GMK file extension is solely used in version 7.0 of GameMaker. Its predecessors used file extension formats, such as GM6, and so on, which can be read by the latest GameMaker program.

The data contained in a file with a GMK extension include:

* Graphics and images used in the game

* Sprites (specific in-game objects)

* Rooms (specifies in-game areas)

* Sounds

* Source codes (additional feature)

* Settings, such as play controls, timing, multiplayer settings, positions, movements, coordinates, and artificial intelligence (AI)

The data inside a .gmk extension has two main objects necessary for the game to be successfully created, and these are:

* The Player Object, which is the sprite controlled by the player.

* And the Control Object that specifies each part that runs the game. This includes player object controls, and so on.

The file with the .gmk extension can be used to compile the game project into its execution form (.exe), but can be kept in a separate directory for possible editions and updates for the game (recompiling the game is necessary to incorporate the changes).

Aside from the keyboard and mouse input devices being used to control the player object in-game, the GameMaker program supports other peripherals, like joysticks, gamepads, and game controllers.
